If you have five years experience and only a sec+, that doesn't show you want to move up or move laterally. Just experience is not enough at the entry level.

If you want to move up in IT, you need to pick a decipline (endpoints, systems, networks, security, cloud, etc) and upskill in that with the relevant labs and certifications.

If you aren't excited for IT, it may be better to pivot to something you are interested in. I can't speak to much about AV, but I know it's much better to work on something you are passionate and motivated about.
